WORK SUPIEORT FOR WRAIPING MACHINES.

Application filed May s, 1923. serial No. 637,658.

To all whom it may concern.:

Be it known that I, GEORGE W. PROUTY, a citizen of the United States, residing at Boston, in thevcounty of Suffolk, State of Massachusetts, have invented a certain new and useful Improvement in Work Supports for Trapping Machines, of which the fol lowing is a specification, reference `being had therein to the accompanying drawings.

This invention relates to wrapping ma chines of the general `type shown and described in my prior applicationfor Letters Patent filed June 21, 1921, Serial No. 479,410, and adapted primarily for wrapping annular objects, such, for example, as automobile tires, coils of wire, etc.`

The present invention has for its object to provide supports for the work to be operated upon, which consist of power driven rollers upon which the work rests and by which it is revolved. The rollers constituting my invention are provided with adjusts able collars which can be simultaneously moved toward and from each other on the said rollers and caused to press against the sides of the various sizes of work to be wrapped. I have also provided auxiliary rollers adaptable for use in wrapping small articles and which can be conveniently at lached and detached from the machine.

The foregoing and other objects of the invention, together with means whereby the same may be carried into effect, will best be understood from the following descriplion of one form or embodiment thereof .illustrated inthe accompanying drawings. It will be understood, however, that the particular construction described and shown has been chosen for illustrative purposes merely, and that the invention, as defined by the claims hereunto appended, may be otherwise practised without departure from its spirit and scope.

In said drawings:

Figsfl and 2 are front and side elevations respectively of the complete machine, show ing in particular the construction constituting my present invention.

Fig. 3 is a plan view of the complete machine.

Fig. 4 `is a sectional view of one of the large work supporting rollers, taken on the line 4--4 of Fig. 1.

Fig. 5 is an enlarged plan view of one of the auxiliary `work supporting rollers and ils associated parts.

Fig. 6 is a fragmentary view of an alternative means for operating the adjustable collars on the rollers. The Vframe of the machine comprises a hase and a yokeV 16 which is pivotally mounted on a shaft 1'? journalled in an upright 18 rising from the'base 15. The yoke 16 is provided with guide rollers 19 for an 24 to which the present invention in part,

relates, and which are driven through. con nections hereinafter more fully described from the motor 23,'thearrangement being such that the work l/V will `be turned relatively slowly with respect to the speed of rotation of the shuttle 20. Said shuttle is formed with a hinged segment `26 normally closing a gap through which the `work W may be inserted, while the yokelGmay be adjusted about the axis of the shaft 17 to center the shuttle with respect to annular objects of differentl sizes, said` yoke'being counterbalanced by a spring 27 and being locked in adjusted position by means of a clamp. 28 carried by an upright 29 rising from the base 15.

The wrapping material, preferably in the form of a continuous strip S of papel', is supplied from a roll 30 supportedby a reel or spindle 31 carried by the yoke 16. Said i paper passes from the roll 30 over a tension device 32, thence through a folding device designated as a `whole by the numeral 38, and thence over a guide plate 34 to the shuttle 9.0. Said shuttle 20 comprises an annulus having on one face a circular series of rollers 35 about which the strip S is wrapped when the shuttle is rotated, said strip being fed from the shuttle about a guide roller 36 to the work 1V. Between the shuttle 2O and the source of supply 30 there is provided a cutting mechanism comprising a knife 37 cooperating with a-portion of the guide plate 84 to sever the strip S when a suflicient length thereof` has been wound around the shuttle rollers 35 to complete the wrapping of the work W. The knife 37 is automatically actuated, after a predetermined numf y "'liell fcranksfl is moved itvvill cause the remaininghell vcranks tohe moved an equal amount, the ytwo bell' cranks of each'pair'.

loer of rotations of the,y driving` dfijslr 21, hy*k a counting mechanismr 38 actuated at each rotation of said driving disk by a cam projection 39 thereon, Said counting,mechanism heing manually adjustable in accordance with the size of the articles- Wrapped From the foregoing the nature, location,

and function of the parts referreditorviill loe;.

Thestandards 40 and 50have journalled therein shafts 4l and j51respec tively, upon vvliichi the Work supporting rollers12l aremonnted. The. rollers-24 are corrugated on their peripheries, as shown in .'lig.y Ll, and yare keyed; tothe shafts l i-.1 and.v

B'ynthe ahovewconstruc- Vtion, the small rollers 70 andeth'eirauxiliary lll() parts can be conveniently placed on the machine and removed therefrom, itbeing understood that when the rollers 70, together.` with the extensions 80 and the shafts T? are removed, sutlicient space is lett `.tor large articles to be placed on the rollers 24. With respect to the roller l0 which is nearest the liront of the machine, l have found it desirable in certain cases to provide but one supporting arm "Z1, the roller being supported thereon by a single shalt i5.

The small rollers are rotated by means ot chains 8l which connect the sprocket Wheels 87 on the shafts il and 5l of the large rollers to the sprocket Wheels 85 on the shafts ot the small rollers TU.

The rollers 70 are also provided Vwith col` lars 88, slidable longitudinally on the said rollers, but caused to rotate therewith by reason ot set screws 89 screwed in the collars 88 and extending into the grooves 90 in the rollers 70. By means of the above construction the collars 88 can be adjusted to lit various sizes ot the small articles to be wrapped.

Certain features shown and referred to herein are covered by claims ot other applications tor Letters Patent as tolloWs:--
